Keep in mind that cache and temporary files exist for a reason; they aren't just junk. They're extra memory for various programs. Yes, they can recompute or redownload everything they need if you delete them, but that takes time that you wouldn't have needed to spend if you hadn't deleted them.

I mean there's nothing especially wrong with CCleaner, but I think it's a bit overzealous. So if you do use it, use it when you need it instead of on a routine basis.

I don't know where temp files are stored on Windows nowadays. I haven't used Windows on a regular basis in years.
